  1. The Past the Present and the Future of Telescope Technology By: Mark Lavery Robin Alexander

  2. History of Telescopes How Does a Telescope Work? Galileo’s Telescope

  3. Introduction…. • Telescope…a system of lenses, mirrors or both used to gather light from a distant object and form an image. • Telescope…Has three major functions-Gather light-provide resolution-magnification

  4. Types of Telescopes: Refracting Galilean- It consists of a convergent lens as objective ( the lens that forms the image); and its eyepiece (or ocular), placed in front of the focus, is a divergent lens Keplerian - eyepiece, or ocular, is a convex (positive, or convergent) lens placed in back of the focus, the point at which the parallel light rays converge; and the instrument produces an inverted (“real”) image that can be projected or made visible.

  5. Types of Telescopes: Reflecting • Newtonian- The Newtonian reflecting telescope contained a small plane mirror that was angled at 45 degrees. This was inside the prime focus and brought the light to the side of the telescope. • Cassegrain- Permits short tubes relative to the mirror diameter. • Gregorian- The Gregorian version of the telescope contains a concave secondary mirror outside of the prime focus. This helps to reflect the light back through a hole into a primary mirror.
